Application tiled September l, 19%. Serial No. 585,778.

`To all 'whomimay/ concern Be 1t known that L Jol-IN Josnrrr Kinney,

`a citizen ot the United States, residing,1 at lluburmin the eountyot Cayuga and State ning jennies, the object being to provide a competent means for feedingv a central inember, such as a marker or thread, in suchwise that the liber will be spun around the saine in a uniform layer whereby the central niember will be completely enclosed and occupy a uni'lorm position in the yarn throughout its length. y

llfhile the invention is primarily designed to insert an identifying` marker such as tape, paper or thread within yarn which is subsequently employed in the manufacture of rope whereby certain advantages are secured over the customary `practice oit insorting the marker between the yarns or between the strands ot the rope, it is not limited to such use as it may with advantage be employed to insert centers ot one kind ot liber in yarns or single strand cords, the outside oit which is made of a different iibei, or the center may be colored ditlerently from the outside.

'llhe type ot nipper adopted 'tor illustratingr the present invention employs the customary bell, grooved jaws yieldingly held together for smoothing' up the yarn and upper and lower nipper steels also yieldingly held together ttor spreading; the 'liber and determining the point where the initial twist shall be `imparted to the yaru llu accordance with the present invention the centerinember of the yarn is ted in through a suitable lgruideway at the point where the liber is spread by the steels and the initial twist commences with the result that the laterally spread. liber wraps around and completely encloses the center in a uniforml layer.

Figure l is a trent view oit the nipper.

Fig. 2 is a side elevation partly broken away and in section looking at the right hand side ot Figure l.

Fig. 3 is a top plan with the upper jaw and upper steel'both removed.

llig. 4C is a bottom plan of the upper nipper steel.

llig. 5 is an elevation looking at the en 60 trance side or rear of the upper steel. The nipper body l0 is ot the usual con struction having` an extended base l1, a threaded lug1 12 for a steel adjusting' screw 53 and an extension 14 to receive the set 6 screw which holds the bell and tube in l place with its cavity in registry with the slot at the top of the support.

The bell 2O is preferably integral with the tube 2l having a triangular vertical slot to receive the two nipper steels and havinga rectangular horizontal slot to receive the two nipper jaws 23 and 24 which are `held in place between the steels and a split retaining` ring 25 secured to the iront of the tube by the screws 26 or similar tastenings.

is is custon'iary in the art the upper jaw member 23 is yieldingly held in engagement with the lower jaw member Z4 by a lever arm 30 pivoted to the holder as at 31 and carrying` a weight which may be held at any adjusted position by set screw Sli. Connection between the lever arm 30 and the upper tube member is here shown as a screweye 36 embracing' the lever arm and threaded into theupper member 23.

rllhe nipper steels 40 and. @til are triangular in cross section and each has a seini-cone shaped bore 4:1 cooperating with the similar bore in the opposed tace ot the other. lt has been found preferable to adjust the lower steel so that its upper tace shall be approximately a sixteenth of an inch more or less below the horizontal center line ci? the yarn so that the horizontal shallow 95 groove a6 in the rear point of the upper nipper steel shallbe in approximately such center line. l small bore l? leads to the apex of the conical enlargement in the tace of the upper steel and receives the central fibers, or as here described, the marker which is to be placed cent 'ally in the yarn, through the rear conical enlargement elf). The bell 2O is slotted as at 50 to 'facilitato the threadinn,l olithe marker into the tube.

rlhe upper nipper steel 4l() is provided vith a relatively heavy lead casting;n of the proper weight, depending1 somewhat upon the character oit the fibery to spread the sliver and to keep it :from twisting` at the center until the lmarker enters. By lowering the lower nippel' steel as stated the marker is ted in the proper place while the sliver is spread and the spread edges begin to twist around the marker. The set screw 53 is adjusted and locked in place by a lock washer in the obvious lnanner.

In operation the initial twist ,is ilnpal'ted to the sliver as it leaves the steels in a somewhatspread and ltlattenelil condition and owing to` the pointed shapecl'f 5these steels the yedges 4of, the sliver vbegin to twist or curl around the center at the point where the Center is fed 2in ywith the result tllat thecenter is enclosed in a complete tibelxcovering. Thetwisting is completed in the .rearend of fthe channel in the jaws and the twisted yarn -is smoothed and Vfinished in its passage through and out of the front 4end of the What I .claim is:

I. In a spinning jenny nippel', a nippel' tube, a plurality oit nippel' steels in said itu-be, and means for feeding` ,a .center rmemfber in proximity to the :apex of said steels ,and `tor vguiding a sliver around said lnelnbel'.

2. In a spinning jellny nippel', a nippel' ltube, a lower steel and an upper steel having .a sliver receiving opening` and also have ing la center vmember receiving and guiding opening .arranged at an angle to the sliver receiving opening and communicating therewith.

3. In .a spinning jenny nippel', a nippel' Lube, a lower nippel' steel and an upper nippel' steel formed with `a conical sliver l'eceiving recess in ythe `proximate faces, one of said steels also lhaving a center member receiving alld guiding opening communicating vwith ,the conical recess in proximity toits apex.

et. In a spinning jenny nipper, a tube, an adjustable pointed lower nippel' steel and a weighted pointed upper nippel' steel with a conical sliver receiving recess in the proximate laces of the steels, the apex of the recess being in proximity to the points7 one ot' said steels also having a center member receiving and guiding opening communieatingy with the conical recess in proximity to its apex.

5. In aespinning` jenny -nipperr` a nippel' tube, a lower nippel steel and an upper nippel' steel, the upper steel being characterized bythe pl'ovision of a groove in its point, said groove merging with the sliver receiving openingl in the upper steel and bcing closed on the lower side to form a `chunnel by the upper tace ot said lower steel, und lneans 'for leerling a center lnenlber to said groove.

G. All upper nippelI steel tor a spinning jenny nippel'` characterized bv the provision oit a semi-conical sliver receivingr opening ill the real' alld bottoni ,laces oll the steel. a marker receiving' hole at all angle to the bounding surface olE the sliver opening. and a groove ill the lower vtace oi: the steel conlnlunicating with the marker vbore and with the apex o't said sliver receivingr opening.

7. rIhe method olE inserting :l central nippel' lnenlber ill a yarn wllicll consists in spreading a sliver in a plane to one side ot the axis of twist, depositing a central lnelnber on said spread sliver and in the axis of twist` and in twisting said sliver about said central lnelnbel' at the point where the central `member is 'ted to the sliver while holding said sliver in lirni contact with lthe central nlelnber at such point but with its edges tree transversely ol' said poillt.
